TFS Build SourceTfs.Checkout

Question

I am trying to get my build to checkout some files (using Microsoft.Sdc.Common.tasks) and then to check them in after the build has finished. But I can't seem to get this working at all, let alone before and after the build.

Whaereabouts should this sort of code live?

  <Import Project="$(TasksPath)\Microsoft.Sdc.Common.tasks" />

  <Target Name="MyProjectDbUpdate">

    <SourceTfs.Checkout  Path="$/MyProject/Code/MyProjectDbUpdate" TfsVersion="2008" workingDirectory="C:\buildagent\MyProject\ContinuousIntegration\Sources\Code" />

Answer 1

Specifying your target as a default target is not going to call it as Team build explicity sets the target it is going to call.

Try renaming the Target to AfterGet or overriding the the GetDependsOn property to include your target

<GetDependsOn>
  $(GetDependsOn)
  MyProjectDbUpdate;
</GetDependsOn>
